BED.

Application filed May 13, 1922. Serial N10. 560,644.

T 0 all whom it may concern.'

Be it known that I, TOM D. ANDERSON, a citizen of the United States, and resident of San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Beds, of which the following is a specification.

My invention relates to a type of folding cot or bed particularly adapted for use by campers and tourists.

One of the objects of my invention is to provide a bed of the character indicated which is entirely made of metal thus assuring a bed of strong rigid construction.

Another object is to provide means whereby the bed maybe securely locked in an open position; also means are provided for securing a strong, flexible spring construction which is extremely resilient while at the same time holding its shape.

Still another object is to provide a resilient spring V'construction which can be readily rrolled up into a small, compact bundle.-

Furthermore it is an object of my invention tov provide a bed of the character indicated which is simple in form, easy| to manufacture and assemble, being of few parts and highly eiiicient in its practical application as well as being readily folded and rolled into an extremely small, compact bundle.

In the drawing Figure 1 is a perspective view of my improved folding bed, in an inverted position, showing the relativepositions of its several parts.

Figure 2 is an enlarged perspective view of the side locking mechanism, parts broken 4o away.,

Figure 3 is an enlarged cross-section taken through one of the end assemblies when folded ready to roll up on a line along the longitudinal axis of the bed.

Figure 4; is an end view of the bed showing the legis being folded in upon the end piece itself. n

Figure f5 is a perspective view showing the side member folded up into the leg member.

Figure 6 is a side view showing the spring element locked to the chain element.

Referring more particularly to the drawing, I show at 1 2 two angle iron end pieces to which are pivotally mounted at points 3 4 5 6 the leg members 7 8 9 1O respectively as shown, these members being` formed of similar angle iron construction having their lower ends flared outwardly as at 11 12 13 14 to form foot members therefor as shown and all being slightly shorter than members 1 2.

Pivotallyl mounted upon leg members 7 8 9 1O are flat iron brace members 12 13 14 15 which have their outer ends formed into hooks which snap over pins 38 39 40 41 on end members 1 2 respectively as shown. These brace pieces when in place upon their respective pins serve to hold the legs rigidly in place the same folding up into their respective leg members as shown in Figure 4L.

At 16 is shown an angle iron side piece which is approximately as long as the end pieces 1 2, the same having a notch 17 in the outer end thereof to engage a pin 18 set into a. second side member 19 both being pivotally mounted upon their respective leg members 7 9 at points 20` 21 as shown.

Upon leg member S is pivotally mounted at 22 a side member 23 which is similar to side member 19 in that it is the same length and has the pin 18 set vtherein as shown, while leg member 10 has a side member 24 pivotally mounted thereon as at 25 the same being provided with the slot 17 as is side member 16, this construction locating said pins and slots in opposed relation to each other as shown.

Slidably mounted upon side members 19 24 by means of a pin 26 workin;` in a slot 27 is an angle iron member 28, the end 29 of which passes through orifices 30 in the members 19 24 as shown. The side mem bers 16-23 have lsimilar orifices as 31 so located than when the two pairs of side members 16-19 and 23-24 are brought. on the same plane, the end 29 of sliding members 28 passes through orifices 30-31 thus lockr ing` the same rigidly together.

Mounted upon end elements 1 2 are a series of springs 32 32 having a number of lines of Chains as 33 secured thereto and running parallel with the side members of ce y the bed as shown. Passing through al link of each row of chains and at right angles therewith and secured to said chains at each end by a collar 34 are a series of resilient wire elements which servek tol hold the chains in a spread position as well as giving greater resiliency to the whole bed.

When it is necessary to fold up the bed the foot is pressed down upon the inverted side members and the sliding member 28 is pulled out from the slots 30-31 thus disengaging the two pairs of side members. Member 23 is then folded up into the leg 8, the brace 13 is unhooked and also folded up as shown in Figure 4, .the leg is then swung inwardly until it parallels endmember 1. The side member 16, Lbrace 12 and leg 7 is now folded in the saine manner and collapses upon the other leg assembly in such a position that it is all securely held together in as small a space as possible in the relative positions shown in the cross-secv tion of Figure 3. The other side members 19-2-l, legs 9-10 and braces 141-15 are folded in thesame manner and then the two end assemblies are rolled up with the chains 33 Iand resilient elements 35, making a small, compact bundle.

At 36 is shown a member secured to the side member 23 and having an upstanding portion 37 formed, thereon which acts `as a guide for side member 211 when the bed is being set up. .The member 36 preventing the members 23-241 from shifting sideways when the strain of the springs being extended is exerted thereupon, thus taking this side strain from the bolts 22--24 and allowing the bed to be set up quickly and easily without danger of breaking at the 'said points of support for the side members 23-24 to the legs 8-10. A similar guide is valso placed upon side member 16, the same not showing in the drawing.

Thus it is seen that I have provided a bed which is strong, rigid when extended, of few parts and easily and quickly disassembled when not in use and rolled up, into a very small, compactbundle easily carried b-y tourists or campers. By constructing the fabric as described the same will never beco-me tangled but will always flatten out without effort because the resilient elements 35 while they provide a certain degree of flexibility in the fabric also persist in reassuming their normal straight condition. The chains being `spaced at all times cannotbecome entangled and the elements 35 offer no opportunity for entanglement such as is offered by the usual coiled spring.

It is to be understood, of course, that while I have herein shown and described one particular `embodiment of my .invention that changes may ,be madein forni, constructon, materials used as well as in manner 0f arrangement and relation of parts therein as is allowed by the scope of the appended claims.

I claim l. A one-piece folding cot comprising a pair of end members L shaped in cross-section, a fabric supported thereby, a leg' L shaped in cross-section pivotally mounted upon each end of each end member, the two legs on each end member folding one into the other and -into the end member into parallel relationship to each other, and a side bar pivotally mounted on Veach leg and L shaped in cross-section whereby to fold into the leg upon which it is mount-ed and into the end member,vthefree len`d-s off the side bars on each pair of side legs being adapted to engage each other, and means forlocking said ends in rigid relation to each other when engaged.

2. A one-piece foldingcot comprisingav pair of end members Lvshaped in cross-section, a fabric supported thereby, a leg L shaped in crosssection pivotally mounted.

3. A one-piece folding cot comprising a shaped in cross-section whereby to fold into the leg upon which it is mounted and into the end member, thesidebar on one leg having a notch rformed in the end` thereof and overlapping the side bar on the correspond-` ing side leg,A a pin on the overlapping side bar to engage said notch, one of each pair of side bars having a slot formed therein and the other havingav bar slidably mounted thereon to engage said slot. c
